Anyways, a proper response: Fusion stats are determined by first adding the two fusee's stats together, then multiplying by 0.6 (60% of the total), then multiplying by: The stats added together are Health, Speed, Damage, Fatigue, Power Level, and Mana.
 * 1) Namekian fusion can only happen once per battle.
 * 2) Hm. Fair enough.
 * 3) Rather than giving the fusion itself the level, I propose we just calc the fusion's stats every time the components level up. Avoids confusion and such. Yes, it means a bit of work every time the fusion fights, but there's less arguments/etc.
 * 4) Of course, the fusion gets the signatures and ultimates. That's a total of 10 sigs and 6 ultimates, assuming no bonuses.
 * 5) Agreed.
 * 6) Again, for purposes of character limits, the fusion still counts as separate characters owned by their respective users. Otherwise, yes, it counts as a single character. This goes for work slots/etc.
 * 7) See #3.
 * For Potara: x1.7 (+70%)
 * For Fusion Dance: x1.65 (+65%)
 * For Merger: x1.6 (+60%)
 * First Namekian Fusion: x1.55 (+55%)
 * Second Namekian Fusion: x1.5 (+50%)

XP is simply added together, and the fusion is considered whatever level they would have with their new XP. For Level 75, it would be Level 75+. Level requirements will be as such:
 * Potara: Must be within 3 levels.
 * Fusion Dance: Must be within 5 levels.
 * Merger: Must be within 7 levels.
 * Namekian: Must be within 10 levels.
