Basically, yeah, LOL!
It's the 4-point/rank version of Mimic, so Gemini can copy all of one target's Powers simultaneously. Not other traits, so no equipment, feats, etc. A quirk of Gemini's psionic construction capabilities; he can temporarily copy special devices but not average equipment......
I considered giving him the 5-point/rank Mimic, but that's substantially more drastic and even I'd be leery of it as a GM. Maybe an alternate power 2-point/rank or 3-point/rank Mimic to copy feats/equipment or something, but for now, I'm just sticking with the original version of his Mimic power. Maybe Gemini could spend a Hero Point for a temporary Alternate Power feat like that for Mimic, anyway, if he really wanted to copy someone's normal equipment and feats.
Minor additional question: Would the Morph power emulate the appearance of a target's clothes, or just their physique/face/etc.? Gemini carries around various outfits for disguise, such as a police uniform (his normal equipment includes some police gear he absconded with at some point).
Anyway, here's a modified version of Gemini, with some tweaks to his powers, feats, skills, and basic stats (factoring in your houserule for Duplication's cost, I dropped the Survival extra and instead threw in the Feedback flaw for some extra points to spend elsewhere).
