30MF Liber Fighter

The 30MF Liber Fighter is an excellent figure that really delivers for its price. The design looks great, assembly is straightforward, and there are lots of options for customization and painting, which makes it especially fun to work with. Overall, it’s a figure that feels well worth the money.
At the moment im at 16 - 30MF figures. So I can say with ease that this one is the best to start out with.

The 30 Minute Fantasy (what did you think MF stood for?) Liber Fighter is a 'Silhouette 3' kit and is mostly only compatible with itself, meaning all the other guys (Archer, Assassin, Knight, Lancer, Priest, Wizard) do *not* have 100% compatibility between parts and they won't all fit right, such as collars, shoulder armor, foot armor, forearm armor and more. It is, however, 100% compatible with the Rosan Fighter kit and 'Class-Up' kits, since they're mostly just a recolor of each other.

The Silhouette 3 body is the shortest one, but also the widest, making him somewhat more dwarf-like, but it also makes him look way stronger and beefier than the Knight, for example. It's not just the body, the head, limbs, feet and hands are all slightly different as well.

Aesthetics:
The Fighter comes in the same grey plastics as the Knight/Priest, but has an orange and clear orange plastic for the collar, rings and gem instead (adding to the dwarf motif, as this represents the 'Earth' element).

The armor color is the same grey as the body color. The heavy armor is more encompassing than any of the others and has a very Dark Souls style to it, with a few spikes, layered (only visually) armor and aggressive shapes, like the sharp knees.
The Knight looks like a swordsman, the Fighter looks like he's there to drink, take out the opposing army by himself and drink again. Not quite a historic full plate armored combatant, but also not exactly high fantasy.

Mechanics:
The Silhouette has a single arm bend (bends most of the way), 180 double knee bend, dual peg disc ankles (double swivel) and 30MS style hands, only much larger. 30MS comparable articulation with somewhat human-like movement/posability, which is more advanced than most Bandai kits in some ways and then have other limitations in others (like the single arm bend).
There are no special gimmicks or functions, the main draw is the modularity of equipment.
The Fighter has slightly hindered knee movement due to its calf-armor and might overall have slightly limited movement compared to the other silhouettes, but it's not a lot.

Equipment:
1 oversized one-handed Great Axe
1 Round Shield or buckler with assorted grips
1 set of full plate armor that covers all of the model's 3mm holes, apart from the ones it adds itself that you can layer onto
6 hands - Holding, fists and open palms
Assorted orange rings with and without pegs

Conclusion:
Out of the 4 30MF kits that I own (the others being the Knight, Priest/Bishop and Wizard) this one is my favorite. I love this kit, he looks like a merciless mercenary, an absolute bruiser who crushes anything that gets in his way, like someone who uses his shield as a weapon, rather than defense.
There are two 'Class-up' upgrades for him, Warrior and Viking, but personally I feel their colors are too mismatching and the parts look a little too exaggerated, but I haven't tried them, so I don't know.
You can technically put other class armors on him, but they don't fit well, while you can also put his armor on others, but again the fit isn't great.
That being said, while swapping armor is awkward, what you can do instead is swap body parts and switch out the limbs or head as you want. It won't look good on the Wizard's black silhouette, but the Liber Priest and Knight use the same grey body color, so that's an option.
