In a campaign I have recently started, one of my players wants to be a character he calls Ironhide, a powersuit that transforms into a van (yes, like the Transformer). He has different abilities in bipedal mode than he does in Van mode, plus his movement and bonuses change, and whatnot... I have a bit of a puzzle as to how we would create such a powersuit type character.
Bipedal mode would give him super-strength, super-con, and immovability, and other such powersuit powers. In van form, he gets alternate movement (he has wheels), laser headlights, and combat sense (internal dashboard radar). not the whole list, but a basic idea. I need to know how I would set up the point system in order to give both modes a full complement of abilities without giving either mode the 'short end of the stick', and without way overspending power points.
Thanks for your time.
