The year 2000, Mantak received an offer from Muzik Box Productions (Malaysia) to release a cassette EP. So Mantak entered the studio and recorded Dark Borneo Art! During the same year, Mantak also recorded 2 new songs for the biggest extreme metal compilation released in Malaysia, Panggilan Pulau Puaka Volume 4, released by one of Malaysia's biggest extreme metal label Psychic Scream Entertainment! The 2 songs recorded were "Thy dance of the bewitched, "And she drinks". After these releases, Mantak's evil symphonies were spreading all over Malaysia and South East Asia!Due to several problems with their current label, Mantak left Muzik Box Productions in 2002 and signed with Nebiula Productions (also one of Malaysia's biggest extreme metal label). In the same year, Mantak entered the studio and recorded their first full length Eye of Deviant. This album received negative reviews from editors and listeners due to the poor sound quality.
In 2003 (Thanks to full sponsorship from Nebiula Productions) Mantak invaded Malaysia’s capital city Kuala Lumpur to work on the recording of their second full length album Polymorphous Perversion in Nebiula Sound Studio. Despite the serious work this is the most enjoyable and craziest studio work ever! Working with a weird, crazy and unpredictable sound engineer, Jadam has never been that easy!
Polymorphous Perversion finally hit the Malaysian extreme metal market in 2003! It is only pressed in cassette format by Nebiula Productions. The CD version was released by an underground label from Germany called Premonition Records, and also released by RA Productions only for Indonesian legions. Polymorphous Perversion was also re-released by a new US extreme metal label called Old Cemetery Records 4 years later in 2007 with a different artwork, including bonus tracks!
LIVE DESECRATION
2002
Playing in Malaysia’s capital city Kuala Lumpur for the first time (which is also as Mantak’s first show outside Sabah!) in the Morbid Fest II with almost 20 peninsular extreme metal bands. There were lots of problems during this show as they left all their equipments at home, which led Mantak lending weapons from the guys in Ephemeral!
Playing in one of the most historical show, with massive maniac attendance ever during Sabah’s metal scene in 2002! Mantak annihilated the stages as supporting act for Damokis and Doxomeddon, the Choice of a New Generation Metal Fest attracted more than 2000 local metal maniacs (This is big for a small scene in Sabah)!Mantak also desecrated several shows in the year 2002. Unfortunately, these performances were not properly documented and not much info is available.
2003
Playing in Kuala Lumpur for the second time as a supporting act for the infamous Impiety to support their Kaos Kommand 696 album during February 2003, alongside Necrotic Chaos, Damokis, Kaliyuga and Nosferial! 
This year Mantak played in Sarawak for the first time for the Sarawak Metal Force 2003 in the oil city Miri, Sarawak. Alongside new and potential sarawakian bands such as Seven Sign & Unitheism, also few more others which are not important enough to be mentioned here!There were numerous stages that Mantak have annihilated during 2000 - 2003, unfortunately we do not remember much about them, and no photos or info of these shows are available!
