Compared to the sharpteeth in the sequels, the Original Sharptooth that made to seem more like a real villain seems to have superpowers.  So, let's list the powers he probably holds and talk about them.

#1. Super Jumping.

He does this 3 times in the movie.  3 times!  First was the long jump to catch up to Littlefoot and Cera.  Second one was when he jumped and landed on top of Littlefoot's Mother, and finally, he uses it again in the final fight when the kids are trying to drown him with a giant rock.  Seriously, a T-rex can't jump as high as he did.  This has just GOT to be a superpower.

#2. Skeletal Invulnerability

He not only survives a long fall, but ends up with nothing broken.  No way that can happen without your bones being invulnerable.

#3. Teleportation.

He disappears completely from the screen in a split-second while Ducky tries to lure him.  There's no way you can make a body of such size disappear so fast without some superpower.

Maybe I'm missing a few, but let's face it!  This guy has superpowers.  In my eyes, it's really not fair to call the ones in the sequels wimps when you compare them to this guy.

1# simple answer, it was a mater of perspective. this being it only looked like a big leap, same with the attack on little foot's mother.  third I believe can be added to a possible adrenaline rush.

2# Another simple answer, he obviously landed on some ledges on the way down that broke his fall.

3#The most logical answer was the location. They were in a cave, one that without a doubt had tunnels in it, one could say sharp tooth merely ducked into one such tunnel and came out behind ducky.

A mechanic engineer type maybe.  Perceptor is more of the pure scientist type from what I've seen.  Though he doesn't appear till part 2 of Island of the Dinobots, while Chip vanishes for the most part.  No real explanation of where the new autobots come from, but one can make up one's own story of what happened offscreen.

the engineer type, then wheel jack is the bot for you also I'll have those autobots show up as military transfers  that Prime ordered.

Rocky smiled as he sat down. He was a bit annoyed at his questions being ignored, but he decided it wasn't worth the fuss. "Yeah i guess friends are good to have around, but being a loner has it's upsides too." Rocky explained. "For example, you don't have to worry about anyone else ending up as Sharp tooth food." Rocky said. "I heard rumors about a talking sharp tooth living here in the valley, I think I heard his name was chomper." Rocky told ducky. "I'd be surprised if a sharptooth really lived here, to me it would seem as safe as having a egg stealer guard a nest." Rocky said as he leaned back, putting his arms behind his head.

" Well nice to meet you shorty." Rocky said. he was a little surprised that Shorty was so quiet. "well I've got to go, I guess I'll see you two later. " Rocky said as he walked away.

Rocky walked until he found were Anna and ducky were sitting by what looked like a camp fire. "Well hello again, I hope your feeling better Ducky." Rocky said to the swimmer. "I just ran into this jerk named Hyp, you know him?" He asked ducky. " I also ran into two long necks named Bron and Shorty." He said to them as he smiled. "Mind if I join you?" He asked the two, not taking his eyes off of Anna.

here's another cybertron alt. mode, this time for Jazz

I think we might be getting off topic folks, so could we please try to stay on topic.

Anyway I think I'll take megatron skywarp and thundercracker. we should start as soon as we got the following rolls filled

Autobots

Bumblebee
Ironhide
Wheeljack
Ratchet
hound
mirage
jazz

Decepticons

reflector( the three camera robots that speak in unionism)


Dinosaurs

Ducky
spike
ruby

Sharpteeth

Redclaw
Thud
Screech

also it will start when the ark crashes into the side of a dormant volcano that is in the great valley and the decepticons come online first and getting their barrings.

"Bron" Bron told Rocky, Shorty still remained silent.

"Nice to meet you Bron." Rocky told the long neck. "You know I meet a long neck who looked a lot like you, I think he said his name was littlefoot." Rocky said, anticipating Bron's response would be that was his son. Rocky turned to Shorty. "So what's your name?" He asked the green long neck.

Lots to choose from.  Certain autobots you want filled first?  Is there the limit to the number of chars someone can play, and from certain category?

No limits, but I would prefer one from at least three category, like one Autobot, one Decepticon, and one dinosaur. Also I think I'll drop the dinosaur alt mode for the characters besides the Dinobots, and ravage. Instead they will stick with cybertronian alt modes.

Two things about that....one is who is Daisy anyway? I don't recall anyone being called Daisy in the movies at least....

And the other thing is that....that does seem a bit harsh, as in, them being murdered and all...I mean, he doesn't really need to do that.  Cause Lotso can just as easily head back to Sunnyside, take control of the place once again while he then finds Buzz, Woody and co and gets revenge on them....well, that's how I would see him get things done that is....as in, gets rid of Ken and Barbie, convinces others to help him in his quest for revenge sort of thing.

I just see no reason for Lotso to go out of his way to actually murder anyone....

Daisy was Lotso's, Chuckles, and big baby's owner before sh lost them at a rest stop, and lotso kills them because she replaced him and he wanted revenge. That and he finds out where she lived, and saw her taking out trash on the garbage truck route.

Nope, only taken characters so far, are Mr. Potato Head and Rex....cause I'm not sure if Kor wishes to have any canon characters, or just his own characters like Godzilla and co.

So if you wish to Lotso, you can Rocky.

as long as no one objects to this

Lotso finds Daisy, grown up and with a husband and children of her own, until Lotso KILLS them in their sleep and burns the house down.

The only known surviving toys will be the characters I control

Megatron(Shattered Glass)
Todd and Tutti Roberts( has been with Daisy since before lotso, chuckles, and big baby were lost)
Hugger- the bear lotso was replaced with, will be tortured by Lotso
AMP suit toy It would be operated like the cars in the second movie, sort of.

this would happen before Lotso joins up with the Prospector and invades sunnyside.
