Absorption sounds a bit too overpowered of an ability in my opinion. Sayuri also already has an energy manipulation ability, so it might end up being a little awkward.
Frankie, for example, has great strength, alarming endurance, and an ability to create plans to react to any situation. However, he's pretty helpless in ranged combat, pretty easy to disable via telekinesis and other psychic powers, and has a serious weakness against water, as well as being knocked into the air. (He refuses to board ships for this reason, although he's okay with aircraft. At least until the Brood get their hands on some powerful air interceptors)
Generally, I think it's healthier for the game when every character has the ability to to defeated by any other character, not just those with obscure abilities and skills. A battlesuit character would have phenomenal strength, but still be subject to being peeled out of his battlesuit, having his battlesuit shut down somehow, or psychic manipulation. A battlesuit with funky invulnerable defensive technologies does not have as many of these weaknesses.
Of course, I'm not the GM, and I tend to be negative about lots of character concepts, so take my advice with a grain of salt! :)
