Duran, I see it differently. I follow the natural Revelation sequence in this case. Beast from the sea was first on the scene. It had a limited lifespan:
Note now the activities of Beast from the earth. It put up an image of Beast from the sea. In my mind that means that Beast from the sea is no more. It then gave breath to the image, the image now becoming a beast in its own right:
The new beast is identified in Rev. 17 as the scarlet-colored wild beast, i.e., Beast from the abyss.
If that is how you see it, it is because you are still stuck on WTS teachings and ignore Scriptures.
The lifespan of the beast from the sea is not limited to 42 months. The 42 months has to do with the said authority that it will be given after it gets healed.
Lifespan is: prior to death-stroke=was>>>>>>>death-stroke=is not>healed=out of the abyss>42-month authority>>after 42 months end kills 2 witnesses/battle with Jesus>thrown into lake=goes off into destruction
[ 8 The wild beast that you saw was, but is not, and yet is about to ascend out of the abyss, and it is to go off into destruction. And the inhabitants of the earth—those whose names have not been written in the scroll of life from the founding of the world—will be amazed when they see how the wild beast was, but is not, and yet will be present.]
[ 13 These have one thought, so they give their power and authority to the wild beast. 14 These will battle with the Lamb, but because he is Lord of lords and King of kings, the Lamb will conquer them. Also, those with him who are called and chosen and faithful will do so.”]
[2 But as for the courtyard that is outside the temple sanctuary, leave it out and do not measure it, because it has been given to the nations, and they will trample the holy city underfoot for 42 months. 3 I will cause my two witnesses to prophesy for 1,260 days dressed in sackcloth.”7 When they have finished their witnessing, the wild beast that ascends out of the abyss will wage war with them and conquer them and kill them.]

[3 I saw that one of its heads seemed to have been fatally wounded, but its mortal wound had been healed, and all the earth followed the wild beast with admiration. 5 It was given a mouth speaking great things and blasphemies, and it was given authority to act for 42 months. 7 It was permitted to wage war with the holy ones and conquer them, and it was given authority over every tribe and people and tongue and nation. 8 And all those who dwell on the earth will worship it. From the founding of the world, not one of their names has been written in the scroll of life of the Lamb who was slaughtered. 10 If anyone is meant for captivity, he will go into captivity. If anyone will kill with the sword, he must be killed with the sword. This is where it calls for endurance and faith on the part of the holy ones.]
[19 And I saw (1) the wild beast and the kings of the earth and their armies gathered together to wage war against the one seated on the horse and against his army. 20 And (1) the wild beast was caught, and along with it (2) the false prophet that performed in front of it the signs with which he misled those who received the mark of (1) the wild beast and those who worship (1) its image. While still alive, they (1,2) both were hurled into the fiery lake that burns with sulfur.]
Note- There is the beast/false prophet (2) and the beast (1) that has a mark and image separate of it. The image is not a beast in itself.
