You do mean:
‘Sonicblight Ganon’

To many it is considered the hardest boss in the game because of it’s signature zig-zag dash attack. Most attacks like the lightning balls and electric metal pillars are fine but you really need to be a parry master if you want to beat that zig-zag.

Phase 1) SURPRISE MOTHERF**KER: you’ll hear Urbosa tell you “watch out, this thing is fast” begore it immediately dashes at you at a speed i would consider well beyond ‘fast’. In roughly a single second, it will dash at you as a blur and strike you, killing you instantly if your hearts are too low. There are only two ways to counter this attack; Parry or Perfect Backflip. If you get the timing wrong, prepare for anal raping by a lighting fast incarnation of all evil. The other attack it uses is EXTREMELY easy to dodge. It will throw three small and slow electric balls at you.

Phase 2) in this phase it’s weapon becomes charged with electricity meaning it disarms your weapon AND shield if it hits, if it manages to disarm you, forget the weapons and swith to a new set as it will already be on top of you by the time you get them back. At the start of phase 2, it will exclusively use an attack where around 10 metal pillars slam into the ground and begin to electrocute. Use Magnesis to pick one up and slam it into Thunderblight, this will knock it to the ground. For the rest of phase two, Thunderblight will do everything he did in phase 1 but with a twist, if it attacks and you miss the parry it goes f**king ballistic and swipes extremely fast, this will deal A LOT of hearts. Sometimes it will also not attack when dashing and instead will shield bash you, look out for this attack and backflip. Last but most certainly not least is the fact it’s dashing will basically be the only attack it uses and it will use it EXTREMELY FAST. If it manages to disarm you, heal and switch, if you try to get your weapons back, you’re as good as dead.

(Fun fact: Thunderblight was the inspiration for the Demon Corpsemakers from the StickNodes Movie Aftermath)
