Alosson's Uberhero mode involves him shooting blue arrows, which explode on impact, similar to Broken Arrow. However, unlike Broken Arrow, arrows fired will not pierce unless certain equipment are equipped.
It is very effective when used with Stagger or Knockback and low attack speed. With certain equipments, Class Skills and Set Skills, his attack speed can reach an extremely fast speed of 0.07 (see Trivia). Furthermore, the longer it is used, the more powerful it gets until the third rhythm input as the arrows increases in volume and velocity.
Note: During Arrow Shower. He will fire at an arc and his arrows can shatter through walls. Alosson can have a disadvantage of this ability in Dungeons because some areas have low ceilings.

Set Skills
Alosson originally equips four Set Skills. At level 20, he can equip another Set Skills, for a total of five Set Skills.
If Alosson has all of his Class Skills obtained, equips Rajinpon's Bow with Oohoroc's Set Skill Lightning Master, Alosson's attack speed will lower to an extremely fast speed of 0.07.
Although Alosson is a DPS (damage per second) unit, none of his Set Skills decrease his attacking speed.
Alosson's Uberhero Mode is the same as Yumipon in Patapon 2, but with a difference: in Patapon 2 the arrows have a green/yellow aura and in Patapon 3 it's blue/light blue. Also, Alosson is faster than a Yumipon Hero with Shubabassa mask.
If you have the all Class Skill obtained, you can perfectly equip a slow bow (e.g the Krakabom Crossbow longbow) and inflict fatal damage in less than 5 seconds.
Alosson can be the fastest attacking unit in the entire game.
Upon Entering Hero mode you can hear him say "ARROW SHOWER!"
