Main article: Scythe

It is the figure which arranged the sickle on the long pole. Overpower your enemies with powerful attacks that take full advantage of the long sword. This variant does not have Thanatos Blade System, but Primary attack is faster than original version.



  • The A mode's animation is similar to SKULL-9.
  • This is the first melee weapon that can perform a 360-degree swing (primary attack) in Counter-Strike Online.
  • When it was first released, there was a bug where the kill icon used Seal knife instead. This bug was fixed in later updates.
    • The HUD icon wasn't replaced as well; placeholders were used instead of its own.
  • It shares the same wall impact sound with the Nata Knife in base form whereas in Thanatos form it is changed to that of the Tomahawk's.
  • The word "THANATOS-IX" is printed on the weapon's handle.
  • The alternative swing animation actually matches with its third person's in contrast with SKULL-9, Green Dragon Blade and JANUS-9.
  • This is the first melee weapon to ever feature more than one wielding animation for both first and third person.
  • This is the second melee weapon which can glow in the dark during Thanatos form. The first one being Beam Sword.
  • When a round ends and you use the B-mode of THANATOS-9, you will hear its stabbing sound non-stop until the next round or the wielder engages the Thanatos Blade System (same as M134 Minigun bug). This also applies for spectator mode.
  • Unlike the SKULL-9, Green Dragon Blade and Wakizashi, the THANATOS-9 is unable to perform the bug-hit.
  • There is a bug that sometimes the user's hands in first-person view is invisible while wielding the THANATOS-9, this also happens in spectator mode as well with the Magnum Drill.
  • There's also a bug when a player dies while using the Thanatos Blade System, the hits will be executed anyway.
