Remind me, was Hero a Blaster or a Tinker? if he was a Tinker he could be either Caster or Archer, if he was pure Blaster then just Archer.
He was a Tinker with the wavelength specialty, made him very good at laser tech presumably, his power was one of the earliest cauldron vials and he was famous when he was alive for being both extremely flexible, and powerful with his tech.
He was given his vial because he was dying from a number of health conditions including diabetes and cancer.
He was also considered to be the first real tinker.
His ability to stretch his specialty in unnatural ways existed probably because it was an unrestricted vial power, and because his shard is said to be Edens "Stilling Shard".
The "Stilling" is one of the Entity's primary and most effective weapons also refered to as their golden beam.
Below is a wiki a copy of the wiki on the Scion's copy of the Stilling Shard.

The Stilling
Scion's primary ability is the power to negate any kind of wavelength using manifestations of golden light. This effect is
extremely versatile; among its uses are the cancellation of heat and sound, the disintegration of molecular bonds, slowing or stopping motion, negating the effects of virtually any parahuman ability,
[3] and disruption of electronics.
[33] At its deadliest, Scion's "stilling" can simply stop all bodily functions in a human, essentially killing them instantly.
[34] Scion's light can be fired as beams, orbs, or area bursts, and can be used as a force field or transmitted by touch; essentially, he can shape his light into any form he wishes.
[3] All of Scion's "stilling" effects are completely silent, including his movements and his attacks.
[35]
Thus Scion's offensive blasts can range greatly in power, from pencil-thin cutting beams
[36] to continent-destroying blasts.
[37] He has practically infinite range as he can shoot across oceans;
[38] his blasts can track targets by curving in mid-air.
[39][40] The detrimental effects of Scion's light lingers, continuing to eat away at any damaged targets.
[41] This lingering effect can kill a man all on its own.
[42] Scion can also use his power defensively, using it to create physical barriers or cancel out the effects of offensive powers.
[3] His stilling can also close portals and even stop the
Simurgh's song.
[43] Finally, Scion's light can have healing abilities, such as when Scion cures a man of cancer
[44] or when he uses his light to heal the capes around him upon his arrival in the
battle against Behemoth.

Weakness of the Stilling
Understandably it's considered to be possibly the most powerful tinker power, infact it's primary weakness is that it manifested as a tinker power severely limiting it effectiveness to what ever Hero can build. Which takes time, resources, money, and the creativity of it user.

Quick history of Hero
In 1988, Hero was introduced to Alexandria and agreed to her idea of forming a government-regulated superhero team with Cauldron's backing.
It's said that Hero and Alexandria where in a significant romantic relationship. (Not sure if fannon or cannon)
Hero was present when Behemoth emerged for the first time in 1992.
In 1993, he was sworn in alongside Alexandria, Legend, and Eidolon as one of the founding members of the Protectorate.
At some point in his career he was a mentor to Armsmaster, and something of a father figure. (Not sure if cannon or fannon)
On September 15, 2000, Siberian bisected him in a confrontation between her and the core Protectorate. Eidolon attempted to heal Hero, but he ultimately died.

Understandably if the grail summons forth legendary heros throughout history, Hero was one of the most powerful and famous of the modern golden age of heros, "the First Tinker" as it where.
