Choujuu Sentai Liveman/Fridge

Fridge Brilliance

 * The Liveman suits don't particularly appear to be battle gear, to put it generously. Of course, they were designed by the wearers in memory of their fallen friends - and their original peaceful goals.
 * Super Sentai Time! It only recently struck me that, in Liveman, they have Animal Mecha for a reason (and on top of that, they're overkill for the reason they were built). Jet Falcon is a jet fighter armed with lasers and talons(!), meaning it can engage in mid-range and melee-range air combat. Land Lion is a quadrupedal lion mecha with useful jaws and two large cannons on its back, giving it mid- and melee-range capabilities. Aqua Dolphin looks like a couple of dolphins attached together, with tank treads as well, fighting with missiles/torpedoes. They are designed to be far more capable than they need to be (a jet that can attack at melee range; what is theoretically - the special effects of the time couldn't possibly show this - the most agile tank ever built; a submarine that can drive up to surface targets). This is because the designers had no idea what they would have to face, and subsequently over-engineered their Humongous Mecha to the point that they didn't need to combine - that they were Combining Mecha at all was an afterthought, installed by their mentor, who foresaw that their enemies might have some sort of humanoid Humongous Mecha. Awesome.
