Normally I avoid the super-simplified transformation ones, but Bumblebee Energon Igniter RotF-style Megatron is actually good in both modes aside from the massive tank gap. Grabbed it and repainted it quickly into BeastWars Rampage, used a spare TM Alpha Trion missile gun for Rampage's tri-barrel rocket launcher AND to fill in some of that tank gap. Not much more to say about it, it was a fun little project. Tank Mode: Rampage, Terrorize!:
can you find something to make depth charge, it is going to be fun seeing the pair race with each other.
