Fake Balance: The three original Humongous Mecha are supposed to be balanced, with Real Robots "Bellzelute" as a light, dodgy sniper and "Coustwell" the somewhat heavier, melee counterpart. "Granteed", the Super Robot, is supposed to be the tanker with balanced weapons on both ends. However, thanks to the AI's tendency to attack units with lower evasion rates, the Granteed and its overwhelming armor rating makes it better than the other two. As a bonus, because it is an L-sized unit, attack and defense bonuses are increased, with weapons so powerful its second strongest is greater than the final attack of the other originals, not to mention good weapon reach that makes it the best sniper, tanker, and melee attacker out of all three.
The actual balance comes in with how the protagonist receives a different set of Spirit Commands depending on whether they're piloting the Granteed or not. On a first playthrough, if the male pilot uses the Granteed, he receives the "Accelerate" Spirit Command note Increase movement by three for one turn, which doesn't quite compensate for the unit's base movement of five. When it finally arrives on the frontlines (or within range of it), it's the best of the three and solidifies its position as the top-tier super, but not before.
The same can be said for the secret fourth unit The Laftkranz which has the qualities of all three other originals. It's an L-Sized unit, meaning it has the firepower and defense of the Granteed. It's also quite dodgy thanks to the Orgone Cloud (which is even available on its predecessor unit the Vorlent) and has a variety of long ranged weapons and a MAP attack. Finally, it isn't lacking in close range attack either, having a Combo Attack and a strong melee attack comparable to the Granteed's, albeit for more EN.
