[HoE] which junker powers fit best?

[RAK3889@ritvax.isc.rit.edu]

hi all, i know i don't post too often, but i got a question I hope ya'll might
be able to give me a hand on. I've got some ideas for junker tech, or more
appropriatly a friend does and wanted to know how to implement them.
Specifically the concepts were making things with transforability
Example: Junker wants to create a suit of armor for templar so when it's
deactiviated it's about the size of a backpack/hip pack, but when templar wants
to be dramatic hits a button, or maybe even a telepathic command and the armor
envelops his torso, arms, legs, and heck give him a helmet too. Has the big red
corss and everything (nifty ain't it?). Or also like trying to create actual
transformers (R) . I know some of the powers that would be used (the obvious
ones) but what could give that power to collapse/transform. Or should i just
make a "transform" power up or a tool trick. Any thoughts would be appreciated. 
thanks
