If Absolute Zero and Colossal Fighter are destroyed together, how do they chain?✓
Both are destroyed simultaneously in battle.
Absolute Zero is mandatory and becomes CL1; Colossal Fighter is optional and becomes CL2.
If Goyo Guardian destroys Colossal Fighter by battle, which effect resolves first?✓
Goyo Guardian destroys Colossal Fighter in battle.
If it is the Goyo player's turn, Goyo is Chain Link 1 and Colossal Fighter is Chain Link 2. Colossal resolves first and can Special Summon itself, leaving nothing for Goyo to take. If it is Colossal player's turn, then it's reversed and Goyo Special Summons Colossal Fighter.

(1) This card gains 100 ATK for every Warrior-Type monster in any Graveyard. (2) When this card is destroyed by battle and sent to the Graveyard, you can Special Summon 1 Warrior-Type monster from either player's Graveyard.
The (1) Continuous Effect re-calculates as the total of Warrior-Type monsters in the Graveyards changes.
This process does not start a chain, even in instances where the ATK gain changes.
VS. "Blackwing - Gale the Whirlwind's" effect is used to halve the ATK of "Collossal Fighter" while he was +400, the (1) Continuous Effect ceases to change the ATK and its value becomes locked at the new value (2800 + 400 = 3200; once halved by Gale = 1600 ATK) so long as "Colossal Fighter" remains face-up.
The (2) optional Trigger Effect activates in Substep 7 - End of the Damage Step when "Colossal Fighter" is destroyed by battle and finally sent to the Graveyard.
This is actually an optional effect, the change being clarified in the DL09 print [REF]].
This effect targets a Warrior-Type monster in the Graveyard and will be negated by "Necrovalley".
This effect can be used to Special Summon the same "Colossal Fighter" that was destroyed, even if he is the only Warrior-Type monster in the Graveyard(s).
The (2) optional Trigger Effect WILL NOT ACTIVATE IF:
"Colossal Fighter" was removed from play After Damage Calculation by "D.D. Warrior Lady’s" effect.
"Colossal Fighter" was destroyed After Damage Calculation by the Flip Effect of "Man-Eater Bug".
A Defense Position "Colossal Fighter" was shuffled into the Deck by "Ehren, Lightsworn Monk".
