* Steelswarm Roach's Effect: Steelswarm Roach negates the Special Summon of a monster, and then it's destroyed.
* Chimeratech Fortress Dragon's Summoning: Chimeratech Fortress Dragon is a Fusion Monster that requires specific materials to be Special Summoned. It doesn't have any specific summoning conditions that could be triggered by Roach's negation.
Scenario:
1. A player attempts to Special Summon Chimeratech Fortress Dragon.
2. Steelswarm Roach activates its effect to negate the Special Summon.
3. Chimeratech Fortress Dragon's summoning is negated and it remains in the Extra Deck.
4. Steelswarm Roach is destroyed as a result of its effect.
Outcome:
* The Special Summon of Chimeratech Fortress Dragon is prevented. The Dragon will not be summoned to the field.
* The player who summoned Roach has lost a monster, but prevented their opponent from summoning Chimeratech Fortress Dragon.
Important Note:
* Even though Steelswarm Roach negates the Special Summon, it does not banish Chimeratech Fortress Dragon. The Fusion Monster remains in the Extra Deck and can be summoned later if the player meets the summoning conditions.
