From the article...bonus to SPD and OCV. The attack power would be a multipower...mostly HAs or HKAs, with some various advantages perhaps. Building up an attack over time can be done in a stacked attack, where, say, its base is 2d6; +2d6 (delayed phase); and +2d6 (full phase). Or something like that. Maybe full phase, then extra segment.
The list of moves...thing is, these are tied to the game controls. Like...the Beowulf Combo I and II are multiple attacks in Hero. Punch, punch, then upward kick (double KB with the target flying UP...which would be a PITA in Hero, as the KB would be scaled back by the target's mass, and by vertical movement rules); or punch, punch, kick that adds Target Falls. In Hero, you'd buy attacks or maneuvers for each of these...but you can combine em any way you want.
