Forum:"Future Fusion and timings"

I have a question. If future fusion is activated and I send like 5 cydras for the summon of Chimeratech Rampage Dragon. When it is summoned, does it miss its timing to pop spell and traps because future fusion has to target it? Since is a "when" effect and not an "if". Also for that same reason. Does my opponent get a summon response window? Or does future fusion target it as it is summoned instead of after.
