The way I have always run them is that they are autonomous, large dog (Labrador) sized synthmorphs that are perfectly capable of being used individually but that really come into their own when combined. Something I think would have been beneficial for them is that, for each additional Flexbot added to the whole they get a bonus to some of their aptitudes. For example, if combined with an additional Flexbot that contains its own Ego they automatically gain the Multiple Personality implant. Each additional Flexbot adds to that collective. As well as gaining the implant they also receive +1 to Speed (not compatible with any other speed enhancers, up to a total of +4), +5 to SOM (up to a total of +15), +5 to REF (up to a total of +10) and +5 to COO (up to a total of +5). So a Flexbot collective that is the combination of 4 Flexbots has the Multiple Personality implant, with the rules applying to all of the Egos residing in the morphs that make it up, +15 to SOM, +10 to REF and +5 to COO. Each Flexbots Durability is handled separately, however any wounds inflicted are suffered by all others. Each Flexbot can be targeted separately in combat, and so you do not have to worry about things like armor. The collective only act during the currently in control Egos action phase.

EDIT: Updated, see below.

When I have gotten it to the point where I am happy with it I will probably submit it to the fanzine, yes. Good idea on a command variant, but what do you mean about temporarily splitting the morphs down without ego shuffling? I rewrote the trait as an update to the Modular Design gear entry, as well as cleaning it up so that it is easier to read, at least I think it is. Thoughts? Modular Design (Enhancement Modification) This morph is designed to lock together with similar modular morphs in different architectural patterns to create larger gestalt forms. When united with other modules, the group is treated as a single morph, with shared capabilities. Morphs with this enhancement can combine with any other morph of the same type as it, as well as any variants of that morph, that are also equipped with the enhancement. When two or more morphs join together using this enhancement and there is only a single ego involved the process is simply a matter of working out the resulting gestalt morphs vital statistics using the method described below. When two or more morphs join together and there are multiple egos involved the resulting gestalt morph also gains the Multiple Personality implant at no cost, and control of the gestalt morph is determined using the rules provided for this implant on page 301 Core. The GM should keep track of which morph each ego resided in before the gestalt was formed as when it is unassembled each ego is automatically returned to that morph. When multiple morphs combine together the resulting gestalt uses a mix of its components abilities and statistics. The gestalt is considered to be equipped with any implant or enhancement any of its component morphs are equipped with, as well as being capable of using any mobility systems its component morphs are capable of. When there is a difference in the speed of a mobility system in the component morphs always use the fastest. Durability is calculated by adding together the durability of each of the component morphs, while the gestalts wound threshold is equal to the highest wound threshold of its component morphs. Death rating is recalculated according to the gestalts new durability rating. If the gestalt is damaged and disassembles without repairing itself all damage is shared equally through the component morphs. This sharing of damage can never outright destroy a morph, it is always left with a durability at least 1 below its death rating. Wounds are applied to each component morph in full. A gestalts morphs advantages are determined by a new statistic line that only appears in morphs with this enhancement. This new line is labeled gestalt advantages in the morphs descriptive text. When a component morph links up with another of its type, these gestalt advantages are applied to the resultant gestalt morph, while the components normal advantages are dropped. Any aptitude bonuses provided using gestalt advantages may not exceed +15 for each aptitude, and they remain limited by the highest aptitude maximum provided by one of the gestalts component morphs. Other benefits such as armor or skill bonuses do not stack, and the highest rated bonus is always the only one applied. EDIT: Sneaky Addition! Redone Flexbots with new variants. Gonna stick them in a spoiler tag because its fairly long. No point making the post really long. EDIT2: Sorry about the constant updates, but I don't want to simply add a new post everytime I think of something. Needed to add a new example for this particular version, so I went Power Rangers and made a Megazord :D One Core (The Body), One Commander (The Head), Two Scouts (The Legs), One Shield (Left Arm), One Bombardier (Right Arm) Flexbot (Gestalt) (Synthetic) Enhancements: Access Jacks, Basic Mesh Inserts, Cortical Stack, Cyberbrain, Chameleon Skin, Direction Sense, Enhanced Vision, Fractal Digits, Mental Speed, Mnemonic Augmentation, Modular Design, Nanoscopic Vision, Shape Adjusting, Weapon Mount (Concealed/Articulated, Built-in Seeker Rifle) Mobility System: Walker (6/24), Hover (8/40), Vector Thrust (6/30) Aptitude Maximum: 40 Durability: 170 Wound Threshold: 8 Advantages: Armor 10/10, +10 SOM, +10 REF, +5 COG, +5 COO
