And they form TFP Soundwave! Laserbeak becomes his chest.

 

maybe lazerbeak, ravage, steeljaw, ratbat, rino combie in into giant warrior

 

The Wreckers. Ultra Magnus as the leader an torso, combines with Roadbuster, springer, Topspin and Bulkhead to form Impactor.

 

A combiner made of all Bumblebee repaints in the universe.

 

LMAO!!! Rotorstorm would've been proud.

 

I think it'd be interesting to see groups like the Decepticon Seekers - Starscream, Thundercracker, Skywarp, Ramjet, Thrust, and Dirge combine  

On the Autobot side, Sideswipe, Sunstreaker, Red Alert, Prowl, Bluestreak and Smokescreen  

 

Main torso:Optimus Prime
Right Arm: Bumblebee
Left Arm: Jazz
Right Leg: Sideswipe
Left Leg: Sunstreaker

EDIT: Combined name: Heroica

 

how about last stand of the wreckers pyro, rotorstorm, top spin, twin twist, iron fist,guzzle, and impactor combine to become a armed to the teeth heavily armored wreckers combiner super warrior named Blitzkrieg

pyro would be the heavy twin cannons hauling rig and battle wagon trailer that would form the core body
impactor would be the tank that would also form the head of the combiner form

twin twist the quad treaded dual drill tank would form the right arm

rotostorm the battle coptor would form the left arm

top spin would form the chest and breastplate armor

with guzzle the tank forming the lower left leg and ironfist the 4wheel drive of road all terrain battle jeep communications vehicle would form the lower right leg

basicly they would model their combiner super warrior form after the combaticons combiner form of bruticus asa starting point and would creae a very much improved heavily upgraded 7 member wreckers combiner form version of it with blitskrieg being a sort of autobot wreckers god guy counterpart to the decepticon combinert bruticus

 

Movie Optimus Prime and Bumblebee. 'nuff said.
