If this card battles a FIRE monster, during damage calculation: This card gains 1000 ATK, during damage calculation only. You can banish this card from your Graveyard; Special Summon, from your hand or Deck, 1 Level 7 or lower Dragon-Type Normal Monster in face-up Defense Position. You can only use this effect of "Carboneddon" once per turn.
But for red-eyes to work with this we need a good way to send it to the graveyard, like using matematician or foolish burial. Also the red-eyes monster is summoned in defense position, it means you must survive your opponent's turn. Or you can use it to Synchro/XYZ summon in the future.
