Remco Crystallis Arets is a Dutch Dota 2 player who plays as a Carry. He won a bronze medal in DreamLeague Season 14 EU DPC: Lower Division and DreamLeague Season 15 DPC Western Europe Lower Division.

Crystallis started his professional career at the end of 2018.

Together with the Ukrainian team Crystallis took part in BEYOND EPIC, BTS Pro Series Season 3: Europe/CIS, and earned silver at ESL Meisterschaft 2020 Season 1.

Crystallis joined Team Creepwave for the new DPC 2021 season. After the team finished third in DreamLeague Season 14 EU DPC: Lower Division, a reshuffle began, which included Crystallis. He spent the second stage of the DPC on the MiLAN Ghost frogs team. The team managed to get through two rounds of qualifications and got a slot at DreamLeague Season 15 DPC Western Europe Lower Division, where Ghost frogs earned a bronze medal. The team finished 9th-12th at qualifying for The International 2021, after which Crystallis left the team. He then moved to Creepwave, where he was able to win gold at Dota 2 Champions League 2021 Season 4 and silver at Dota 2 Champions League 2021 Season 5.
