The Maximum Series is a sub-line of Beyblades in the Metal Saga series, specifically Beyblade: Metal Masters, in which one of the parts are considered the best of a certain attribute, hence the name, Maximum. The series consists of HD Academy Beys: Twisted Tempo 145WD, Flame Byxis 230WD, Hades Kerbecs BD145DS, Evil Befall UW145EWD and Spiral Capricorn 90MF.
Flame Byxis is part of the Maximum Series because it has the tallest Spin Track, measuring 23 millimeters.
Twisted Tempo is part of the Maximum Series because its Fusion Wheel is the heaviest non 4D wheel, weighing 47.84 grams.
Hades Kerbecs is part of the Maximum Series because its Fusion Wheel is the widest non 4D wheel, measuring 50 millimeters.
Evil Befall is part of the Maximum Series because its Performance Tip is said to be best for Stamina purposes.
Spiral Capricorn is part of the Maximum Series because of its Performace Tip Metal Flat (MF), allowing this Beyblade great speed and powerful upper smash attack.
- Hasbro released the Maximum Series Beys, however, without the Maximum Series branding.
