Celsius is the Summon Spirit of Ice in Tales of Symphonia. She can be found in the Temple of Ice. Sheena Fujibayashi can only summon Celsius or any other summon spirit while she is in Over Limit mode. When Sheena decides to summon Celsius she says the following words. "I call upon the disciple of everlasting ice! I summon thee, come Celsius!" When she is summoned, Celsius slams her hand on the ground and shards of ice come out and hit the enemies.
